There are a number of airports around the world that are smarter than CDG whereby they declare certain non-Schengen arrivals "clean" and pax don't have to go through security again. For instance, for arrivals from USA, Canada, Singapore, Japan, I believe also UK, and certainly some others, passengers connecting in FRA, MUC, ZRH and I think also AMS do not go through security again. But that would be a bit too customer-friendly for CDG, so, no, not there. AF would love that, as it would make 2E-2F connections a little less stressful, taking out one of the two possible bottlenecks (there still would be immigration).
